چکیده
This study was conducted to examine the effect of different wheat straw and concentrate proportions on feed intake, nutrient digestibility, growth reproductive performances F1 cross breed (Boran X Friesian) dairy heifers. Wheat (WS) with 93% dry matter content chopped (3-5 cm in length) mixed concentrate, molasses water. The amount water used for preparation total ration three fold amount. Twelve heifers (90.45 ± 7.37 kg LW, mean ±S.D) were randomly assigned one dietary treatments (WS80= 80% WS: 20% concentrate; WS60 = 60% 40% concentrate) WS40 (40% a completely randomized block design. diets offered ad-libitum allowing 15-20% refusal. experiment consisted 345 days feeding trial 7 measurement digestibility.

متن کاملInfluence of forage level and naloxone injection on feed intake, digestion, and plasma hormone and metabolite concentrations in dairy heifers.
Four ruminally cannulated Holstein heifers (287 +/- 26 kg) in a 4 x 4 Latin square were used to evaluate the effects of naloxone injection and forage level on dietary intake, ruminal fermentation characteristics, digestibility, and plasma hormone and metabolite concentrations. Treatments were arranged in a 2 x 2 factorial with naloxone injection (0 vs .3 mg/kg; saline vs naloxone, respectively)...

This experiment aimed to describe the effects of Oregano extract (OE) inclusion into the concentrate fed to dairy heifers on physiological parameters, feeding behavior, intake, and performance. Thirty-two Holstein heifers were randomly distributed into four treatments: C = control, without addition of OE; OE2.5 = 2.5 g; OE5.0 = 5.0 g and OE7.5 = 7.5 g of Oregano extract per heifer/day.
